Always reset ANSI colors in progress-bar line
When having a message like `waiting for a machine to build X` and
building with `nix build -L`, the log-prefix is always colored yellow[1]
on a small terminal-width as everything (including the ANSI color-reset) is
stripped away.

To work around that problem, this patch explicitly adds an `ANSI_NORMAL`
to the end of the line.

which user files Nix will load during startup.

never use /var/folders for TMPDIR on darwin
This doesn't just cause problems for nix-store --serve but also results
in certain build failures. Builds that use unix domain sockets in their
tests often fail because the /var/folders prefix already consumes more
than half of the maximum length of socket paths.

    struct sockaddr_un {
       sa_family_t sun_family;               /* AF_UNIX */
       char        sun_path[108];            /* Pathname */
    };

Eelco Dolstra bbe97dff8b Make the Store API more type-safe
Most functions now take a StorePath argument rather than a Path (which
is just an alias for std::string). The StorePath constructor ensures
that the path is syntactically correct (i.e. it looks like
<store-dir>/<base32-hash>-<name>). Similarly, functions like
buildPaths() now take a StorePathWithOutputs, rather than abusing Path
by adding a '!<outputs>' suffix.

Note that the StorePath type is implemented in Rust. This involves
some hackery to allow Rust values to be used directly in C++, via a
helper type whose destructor calls the Rust type's drop()
function. The main issue is the dynamic nature of C++ move semantics:
after we have moved a Rust value, we should not call the drop function
on the original value. So when we move a value, we set the original
value to bitwise zero, and the destructor only calls drop() if the
value is not bitwise zero. This should be sufficient for most types.

Also lots of minor cleanups to the C++ API to make it more modern
(e.g. using std::optional and std::string_view in some places).

* Sets the tarball-ttl to infinity (ensuring e.g. that the flake

* Disables retrying downloads and sets the connection timeout to the
  minimum. (So it doesn't completely disable downloads at the moment.)

Modularize config settings
Allow global config settings to be defined in multiple Config
classes. For example, this means that libutil can have settings and
evaluator settings can be moved out of libstore. The Config classes
are registered in a new GlobalConfig class to which config files
etc. are applied.

Relevant to https://github.com/NixOS/nix/issues/2009 in that it
removes the need for ad hoc handling of useCaseHack, which was the
underlying cause of that issue.

Matthew Bauer 8f186722a9 Set backup MANPATH in case man path isn’t set correctly.
Previously, this would fail at startup for non-NixOS installs:

nix-env --help

The fix for this is to just use "nixManDir" as the value for MANPATH
when spawning "man".

To test this, I’m using the following:

$ nix-build release.nix -A build
$ MANPATH= ./result/bin/nix-env --help

Sergei Trofimovich c9857ef262 src/libmain/stack.cc: fix 'ucontext' usage on glibc-2.26
Build fails as:

$ make

src/libmain/stack.cc: In function 'void nix::sigsegvHandler(int, siginfo_t*, void*)':
src/libmain/stack.cc:21:21: error: 'ucontext' was not declared in this scope
     sp = (char *) ((ucontext *) ctx)->uc_mcontext.gregs[REG_RSP];
                     ^~~~~~~~
src/libmain/stack.cc:21:21: note: suggested alternative: 'ucontext_t'
     sp = (char *) ((ucontext *) ctx)->uc_mcontext.gregs[REG_RSP];
                     ^~~~~~~~
                     ucontext_t

It's caused by upstream rename:
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=251287734e89a52da3db682a8241eb6bccc050c9

which basically changes
    typedef struct ucontext {} ucontext_t;
to
    typedef struct ucontext_t {} ucontext_t;

The change uses ucontext_t.

Tuomas Tynkkynen 2cd468874f Include config.h implicitly with '-include config.h' in CFLAGS
Because config.h can #define things like _FILE_OFFSET_BITS=64 and not
every compilation unit includes config.h, we currently compile half of
Nix with _FILE_OFFSET_BITS=64 and other half with _FILE_OFFSET_BITS
unset. This causes major havoc with the Settings class on e.g. 32-bit ARM,
where different compilation units disagree with the struct layout.

to do locking.

Eelco Dolstra fa7cd5369b StoreAPI -> Store

Eelco Dolstra c10c61449f Eliminate the "store" global variable
Also, move a few free-standing functions into StoreAPI and Derivation.

Also, introduce a non-nullable smart pointer, ref<T>, which is just a
wrapper around std::shared_ptr ensuring that the pointer is never
null. (For reference-counted values, this is better than passing a
"T&", because the latter doesn't maintain the refcount. Usually, the
caller will have a shared_ptr keeping the value alive, but that's not
always the case, e.g., when passing a reference to a std::thread via
std::bind.)

Eelco Dolstra d34d2b2bbf Use posix_spawn to run the pager
In low memory environments, "nix-env -qa" failed because the fork to
run the pager hit the kernel's overcommit limits. Using posix_spawn
gets around this. (Actually, you have to use posix_spawn with the
undocumented POSIX_SPAWN_USEVFORK flag, otherwise it just uses
fork/exec...)

Shea Levy 64e23d0a38 Add download-via-ssh substituter
This substituter connects to a remote host, runs nix-store --serve
there, and then forwards substituter commands on to the remote host and
sends their results to the calling program. The ssh-substituter-hosts
option can be specified as a list of hosts to try.

This is an initial implementation and, while it works, it has some
limitations:

* Only the first host is used
* There is no caching of query results (all queries are sent to the
  remote machine)
* There is no informative output (such as progress bars)
* Some failure modes may cause unhelpful error messages
* There is no concept of trusted-ssh-substituter-hosts

Eelco Dolstra 2bd0fcc966 Use libnix as a prefix for all Nix libraries
In particular "libutil" was always a problem because it collides with
Glibc's libutil.  Even if we install into $(libdir)/nix, the linker
sometimes got confused (e.g. if a program links against libstore but
not libutil, then ld would report undefined symbols in libstore
because it was looking at Glibc's libutil).
